Questions about NF-e Extractor.

What is an NF-e, and what is the chave de acesso?

It is the authorized Brazilian electronic invoice (Nota Fiscal Eletronica), cleared by SEFAZ under layout 4.00. The extractor reads the 44-digit access key (chave de acesso) used to validate and track the document at SEFAZ, the document number and series, the document model (55 for NF-e, 65 for the consumer NFC-e), the layout version, and the environment type (1 production, 2 homologation).

Which issuer and recipient fields come out?

The supplier and buyer legal name, tax ID (CNPJ, 14 digits, or CPF), and state registration (Inscricao Estadual), the issuer tax regime (1 Simples Nacional, 3 Regime Normal) and the buyer IE indicator, the issuer state (UF) IBGE code and the tax-fact municipality IBGE code, and the operation nature (such as VENDA or DEVOLUCAO) and operation direction (0 inbound, 1 outbound).

Are the line items returned with the Brazilian tax codes?

Yes. The line items table returns each product with its product code, barcode (GTIN), description, NCM code (the Mercosur tariff classification), CEST code, CFOP code (the operation code), unit, quantity, unit price, line amount, and the ICMS base amount, rate, and tax amount.

Which totals and taxes come out?

The invoice grand total, the products total, the discount and freight amounts, the ICMS tax base and total ICMS amount (ICMS is the Brazilian state VAT), the approximate total taxes (the Lei 12.741 transparency figure), the freight modality and carrier, and the payment method (01 cash, 03 credit card, 10 bank transfer).

What standard does it follow, and what are the limits?

The field set is modeled on the authorized NF-e document (the procNFe layout 4.00 XSD package and the Manual de Orientacao do Contribuinte). PDF only, up to 10MB and 100 pages, and the invoice is not retained after extraction.

Doing this to one file, or to ten thousand?

The tool reads a single document. The platform reads the whole estate once and keeps it queryable — the same engine, with a memory.

See document data extraction if you run this for risk and compliance teams, or the extraction API if you are building it in.
